My wonderful Meg kitty.

Athena, you're wrong.

First, the original text:
(15:19:25) Athena: Do you know what is special about 196?
(15:19:45) CERisE8192: It's 14^2
(15:19:56) Athena: well, there's that
(15:20:37) Athena: But also, it's not a palindromic number, and never becomes one no matter how many times you flip the digits and add it to itself
(15:20:49) Athena: Every positive integer that comes before it is
(15:20:56) Athena: In base 10 at least
(15:21:02) Athena: brb
(15:23:43) CERisE8192: Hmm.   I'm not certain if I believe that.  What differentiates it from 169 (13^2)?
(15:32:21) Athena: 169 + 961 = 1130
(15:32:45) Athena: 1130 + 0311 = 1441
(15:32:49) Athena: see?
(15:32:58) CERisE8192: Oh!  That sort of flipping digits.
(15:33:04) CERisE8192: Hmm.  I'm not sure if I believe that.
(15:33:14) Athena: just try
(15:33:22) Athena: 196 never becomes palindromic
(15:35:12) Athena: 196 + 691 = 887
(15:35:44) Athena: 887 + 788 = 1675
(15:36:13) CERisE8192: Tsk.  This is precisely what computers are good at.
(15:36:22) Athena: yeah good point
